Five insecticides (pyriproxifen, imidacloprid, deltamethrin + heptenophos, lambda-cyhalothrin and Bacillus thuringiensis Berliner subsp. tenebrionis) were examined in the laboratory for their acute detrimental side-effects at field rates on adult seven-spot ladybird beetle, Coccinella septempunctata L. The toxicity of the preparations was determined by measuring the acute surface contact effects (dried spray on leaves of Philadelphus coronarius L.), except for B. thuringiensis where mixed pollen was treated. Four to six concentrations were tested (pyriproxifen 12.5, 25, 50, 100, 200, 400 mg AI litre(-1); imidacloprid 62.4, 125, 250, 500 mg AI litre(-1); deltamethrin + heptenophos 26.4, 53.1, 106.3, 212.5 mg AI litre(-1); lambda-cyhalothrin 1.1, 3.4, 10, 30 mg AI litre(-1); B. thuringiensis 1.5, 3.0, 12.0, 48, 192, 768 mg AI litre(-1)), with 22 adults exposed per concentration. All tests were conducted in the laboratory of the Plant Protection Department (University of Debrecen, Hungary) at 22-25 degrees C, 40-60% RH, under a 16:8 h light:dark photoperiod in 1998-1999. Data were analyzed by probit analysis, probit transformation and analysis of variance. According to different categories of evaluation, pyriproxifen, imidacloprid and B. thuringiensis subsp. tenebrionis seem to be safe for C. septempunctata adults but the other two preparations were moderately harmful to them, which requires further semi-field or field tests to measure their real effect under field conditions.
在实验室中，对五种杀虫剂（吡丙醚、吡虫啉、溴氰菊酯+庚烯磷、高效氯氟氰菊酯和苏云金芽孢杆菌柏林亚种暗黑亚种）以田间使用剂量对七星瓢虫成虫（Coccinella septempunctata L.）的急性有害副作用进行了检测。除苏云金芽孢杆菌处理的是混合花粉外，通过测量急性体表接触效应（将干燥喷雾施用于欧洲荚蒾叶片上）来确定制剂的毒性。测试了四至六个浓度（吡丙醚12.5、25、50、100、200、400毫克有效成分/升；吡虫啉62.4、125、250、500毫克有效成分/升；溴氰菊酯+庚烯磷26.4、53.1、106.3、212.5毫克有效成分/升；高效氯氟氰菊酯1.1、3.4、10、30毫克有效成分/升；苏云金芽孢杆菌1.5、3.0、12.0、48、192、768毫克有效成分/升），每个浓度处理22只成虫。所有试验于1998 - 1999年在匈牙利德布勒森大学植物保护系实验室进行，温度为22 - 25摄氏度，相对湿度为40 - 60%，光周期为16:8小时光照:黑暗。数据通过概率分析、概率转换和方差分析进行分析。根据不同的评价类别，吡丙醚、吡虫啉和苏云金芽孢杆菌暗黑亚种对七星瓢虫成虫似乎是安全的，但另外两种制剂对它们有中等危害，这需要进一步进行半田间或田间试验以测量它们在田间条件下的实际效果。
